Option nr.2 is the best from all angles. Free software, excellent modularity, excellent online documentation, huge blueprint "database". Instead of Arduino UNO R3, you can use a Nucleo board and gain in speed (with the required grbl version built for STM32) just by moving the shield from a board to another, matching industrial solutions.
